# At What Temperature Does Running Water Freeze?

Ice starts to form in pools of water at about +4 degrees C. Once the water reaches 0 degrees C (32 degrees F), it will start to freeze on the surface, forming a sheet of ice which insulates the rest of the water, so it tends not to get any colder. If you poured a cup of water out of a window with the air temperature outside at -40 degrees F, the water would freeze before it struck the ground.
